Hi all,
Surely there must be some upper time limit over which the computation of
the first moment of the spectrum has any meaningful value to the
psychoacoustician. For example, time-reversed versions of many stimuli are
perceptually very different, yet have identical first moments if computed
over the full duration of the stimuli. Seems like one would have to
compute a running first moment over time to differentiate such stimuli on
the basis of their first moments.
Cheers,
